LCOMOTIVE-TENDEER TANK.

Specification of Letters Patent.

Patented June 13,

Application filed March 10, 1916. Seria] No. 83,377.

To all whom t may concern:

Be it known that I, WILLIAM J. ToLLnR- rrox, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Locomotive-Tem der Tanks, of .which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

The present invention has relation to lo' comotive tender tanks of that type in which the tank is of rectangular shape. In locomotive tanks of this character, as heretofore constructed, it is customary to unite .the plates that constitute the sides of the tank with the plates that constitute the bottom, by means of a corner angle iron to which the bottom and side plates are respectively riveted, and with such type of tanks it is customary to reinforce the vertical walls of the tanks by T irons riveted thereto, these T irons terminating just above the ,bottom angle iron that connects the side and bottom plates of the tank. This prior construction of rectangular'tanks is objectionable for several reasons. 'In the first place, when the side plates and bottom plates are riveted to an angle iron, two seams are formed along the bottom of the tank, both of which seams offer danger of leakage and y are of such nature as to render it difficult to calk them. Again, where T iron stifeners' are employed it is found in practice that the constant vibration of the tank under the .stresses and strains to which it is subjected is apt to cause a cracking of the side plates just between the lower end of the vertical side stiti'eners and the angle iron that forms the bottom corner of the tank.

My present invention has for its object to provide a locomotive4 tender tank of simple and effective construction wherein the objections incident to prior tanks shall be avoided.

To this end the invention consists of the features of novelty hereinafter described, illustrated in the accompanying drawings and pointed .out in the claims at the end of vthis specification.

Figure l is a View in side elevation of a locomotive tender tank embodying my invention. Fig. 2 is a detail perspective View showing one of the bottom corners ofthe tank with the plate closing said corner omitted. Fig. 3 is an enlarged detail Viewl in vertical section, through one of the bottom corners of th tank. Fig. 4 is an enlarged View in vertical cross section on line 4 i of Fig. 1. Fig. 5 is an enlarged view in vertical section showing the lapping of the side and bottom plates, one of the stringers being shown in elevation. Fig. 6 is an inner face view showing the lapping joint of the bottoni and side plates. Fig. 7 is a View in cross section on line 7-1-7 of Fig. 5.

Referring to the accompanying drawings A designates the side plates or walls of the tank and B denotes the bottom of the tank. Each of the sides and bottom of the tank may consist of a single plate or a plurality of plates depending upon whether sheets `of suitable size can be secured.

As shown, the bottom B has its corner edges upturncd, the radius of the corner being preferably in the neighborhood of live inches and preferably the upturned edges of the bottom plate are cut or beveled off as at at points where'the T irons cross such edges. The upturned edges of the bottoni plate B are united by rivets C to the flared lower edges of the side walls A of the tank. Transversely of the tank extend the stiffeners D that are preferably of T iron construction. As shown, these stiffeners extend vertically along the side walls of the tank and across the bottom of the tank and are continuous, the lateral flanges (l of the stiieners being riveted to the bottom and sides of the tank at proper intervals.

In bending upward the edges of the bottom B of the tank, I prefer to cut out the corner portions of the bottom as shown at b4 in Figs. 2 and 3 of the drawings, 'to permit the more ready upturning of theedges of the bottom. The opening b thus formed, as shown in Fig. 2, will be closed by a corner plate E (see Fig. 3) that may be a casting having a portion e that lits within the corner opening b and having flanges that are riveted as shown, to the bottom and side plates of the tank.

From the foregoing description it will be seen that mf improved tank possesses the following advantages. In the first place, the bottom of the tank having its edges bent upward and being riveted to the side plates, the two inaccessible seams (incident to prior constructions) at the junction of the bottom and sides are avoided and a single seam only is necessary, thereby not only decreasing the initial cost of construction but decreasing also the danger of leakage and the cost of calking the joints between the usual corner angle irons and the side Walls and bottom of the tank. Again, the stilening ribs, extending as they do around the side walls and bottom of the tank, afford an extremely rigid construction which obviates the danger of cracking of the side Walls incident to the strengthening of the side walls by stiffeners of prior construction. It is not essential to my invention in its broader aspect that the corners of thebottom should bev cut away as shown, nor isy it essential that both the ends and the sides of the bottom should be upturned although this is done in the preferred and most effective form of the invention.

It is obvious that the precise details of construction above set out may be modified without departing from the scope of the invention and that features of the invention may be employed without its adoption as an entirety.

. Having thus described my invention,

stiil'ener irons extending over said side Walls and said bottom and riveted thereto.

2. A locomotive tender tank comprising side and end Walls and a bottom, said bottom having'pal'ts of its edges beveled and bent upward to a distance above the bottom line of the tank and riveted to the lower edges of the side Walls, and stiffener irons located within the tank and extending over the beveled portions and over the side walls and across the bottom and riveted to said side walls and bottom.

3. A locomotive tender tank comprising side and end walls and a bottom .riveted to said walls, said bottom having its edges bent upward to a distance above the bottom line of the tank, the corners of said bottom being cut away, and corner plates connected to said walls and bottom of the tank.
